Filter Response Panels - Tannoy QFLEX User Manual

Buttons
Buttons generally have two states; depressed (active) and non-depressed (inactive). Generally, the button will apply the
condition that is labelled when it is depressed. The space bar may be used to activate a button which is in focus.
Radio buttons
These are laid out in mutually exclusive groups to select one of a number of options. Press the radio button to select it,
which will cause any other button in the group to be deselected. Once a control in the group is highlighted, the PGUP,
PGDWN and Arrow keys may also be used to change the selection.
Faders
Faders provide a linearly traversing button, which may be dragged using a pressed mouse to adjust the value. These
sometimes also have an associated value box for showing the numerical value of the parameter. Once the control is
highlighted, the PGUP and PGDWN keys may be used for coarse adjustment, and the Arrow keys or the mouse wheel
may be used to for fine adjustment.

8.17 FILTER RESPONSE PANELS

Some panels provide a graphical representation of the response of one or more of the filters/equalisers in the device.
These will usually consist of coloured semi-transparent filled areas representing individual filters, overlaid with a white
curve line representing the overall response of a bank of filters/equaliser sections.
When the associated filter parameters are adjusted, you will see the curves responding so they always show the current
response.
It will usually be possible to 'drag' the filter parameters with the computer mouse directly on the Response Panel. If you
click anywhere in a Response Panel, you will see a set of 'drag handles' appear at the apexes of the individual filter
response curves. These handles will usually have the same colour as the filter they relate to, and carry a number or letter
to assist identification.
To change a filter parameter, place the mouse pointer over the drag handle, then press and hold the left mouse button
while moving the mouse (vertically to change the filter gain, and horizontally to change the filter frequency). The filter
With/Slope/Order may be adjusted either using the mouse wheel, or by holding the keyboard shift key whilst dragging the
handle vertically.
The keyboard may also be used (see Keyboard Shortcuts).
Copy Graphics
To assist in preparing documentation etc, any response panel may be copied (to the Windows clipboard) by right-clicking
on the panel and selecting Copy Image to Clipboard. The bitmap image may then be pasted into another application
(such as word-processing), usually by selecting Edit>Paste in that application, or CTL+C.
Copy/Paste Settings
You can copy EQ settings from one channel to another on a given device, or copy EQ settings from one device to
another. To do this simply right-click on the source panel (the one you want to copy from) and select Copy EQ Settings.
Then on the destination response panel (the one you want to copy to), right-click and select Paste EQ Settings. You will
be alerted to any problems such as the destination response panel not having enough EQ bands to reproduce the source
EQ, or access to some or all of the bands being restricted due to security protection.
